Junkyard Find: 1985 Mercedes-Benz 300D Turbodiesel With 411,448 Miles

I like to search for junkyard vehicles with exceptionally high final odometer readings, a task made more difficult by the fact that just about every manufacturer besides Volvo and Mercedes-Benz used five-digit odometers well into the 1980s. Even in the middle 1980s, most cars weren’t really expected to hit the 100,000-mile mark … unless they were Mercedes-Benzes with diesel engines, in which case their owners expected them to make it to 300,000 miles. Here’s an oil-fueled W123 in Colorado that exceeded even that expectation.

Yes, that’s 411,448 miles showing on the clock. I’ve seen discarded Mercedes-Benzes that beat this figure (for example, this gas-engined W201 with 601,173 miles, this diesel W126 with 572,139 miles, and this diesel W126 with 535,971 miles), and I’ll bet many of their brethren with missing instrument clusters and/or from the five-digit-odometer 1960s) bested those numbers. I find plenty of 300k+ Hondas and Toyotas, of course, and even this surprising 363,033-mile Olds Calais, but the 400,000-Mile Junkyard Club is a very exclusive one. I’ve seen this Volvo 740 Turbo Wagon with 493,549 miles, this second-gen Honda Accord with 411,794 miles, and this 411,344-mile Toyota Tercel 4WD Wagon in recent years, plus a 1989 Pontiac LeMans that belongs in a junkyard yet will probably hit the 400k mark on the race track in the next couple of years.

1985 was the last model year for the legendary W123a, a fact I was able to look up in the junkyard without even going online. This 300D’s final owner printed out the entire English Wikipedia page for the W123 and kept it in the car. Was this to wave at prospective buyers intimidated by the astronomical odometer figure, or just to provide documentation for the driver to wave around when bragging to passengers about their amazingly reliable car? We’ll never know.

As is the case with most extreme-high-mile cars, this one had a lifetime of devoted maintenance and looked pretty clean even in the junkyard. All the factory-issue manuals were still in the glovebox after 35 years.

The keys were still in it when it reached this place, which— most of the time— means that the car was a dealership trade-in that no auction buyers would touch after its former owner left the lot in a new ride. A decades-old non-truck with absurdly high miles and a diesel engine won’t get much interest from used-car shoppers these days, particularly in AWD-crazed Colorado. Next stop, junkyard!

The interior looks nice, and the indestructible MB-Tex upholstery still thinks it’s February of 1985, when this car rolled off the assembly line in West Germany.

There’s some body-filler-and-paint rust repair in the typical corrosion spots, not as bad as some of the abominations I’ve seen but presumably done after the car depreciated to a very low level in our current century.

Since it appears that this car lived in New England at some point, that rust doesn’t seem so bad.

Here it is, the nearly immortal OM617 five-cylinder turbodiesel engine. This one was rated at 125 horsepower and 181 pound-feet when new, and I’ll bet it still worked fine when the forklift dropped this car into its final parking space. Sadly, it never had a chance to do any road-racing, a task at which the OM617 excels.

How much would you have paid for this car in running, driving condition? We’ll consider that the Question of the Day.

    A co-worker still has one of these, same color but his is an 81-82. Too bad his 300SD looks very beat up with washed out front fenders and some OEM but not period correct chrome alloys but mechanically speaking is a tank. He actually daily drives it. He's one of those guys who likes old Benzes and wouldn't sell his but has other priorities right now.

    Highest mileage I have seen was a Crown Victoria taxi. Odometer was showing 469,000 km and there was a sticker in the door jam showing the dealer had replaced the odometer at 712,000km and reset the new odometer to zero. A total of 1,181,000 km or 733,839 miles.

      Years ago there was a guy in the Midwest who did something like 1.1 million document miles on an early 80s Townie.

  • Kwik_Shift_Pro4X Thankfully I don't have to deal with GDI issues in my Frontier. These cleaners should do well for me if I win.
  • Theflyersfan Serious answer time...Honda used to stand for excellence in auto engineering. Their first main claim to fame was the CVCC (we don't need a catalytic converter!) engine and it sent from there. Their suspensions, their VTEC engines, slick manual transmissions, even a stowing minivan seat, all theirs. But I think they've been coasting a bit lately. Yes, the Civic Type-R has a powerful small engine, but the Honda of old would have found a way to get more revs out of it and make it feel like an i-VTEC engine of old instead of any old turbo engine that can be found in a multitude of performance small cars. Their 1.5L turbo-4...well...have they ever figured out the oil dilution problems? Very un-Honda-like. Paint issues that still linger. Cheaper feeling interior trim. All things that fly in the face of what Honda once was. The only thing that they seem to have kept have been the sales staff that treat you with utter contempt for daring to walk into their inner sanctum and wanting a deal on something that isn't a bare-bones CR-V. So Honda, beat the rest of your Japanese and Korean rivals, and plug-in hybridize everything. If you want a relatively (in an engineering way) easy way to get ahead of the curve, raise the CAFE score, and have a major point to advertise, and be able to sell to those who can't plug in easily, sell them on something that will get, for example, 35% better mileage, plug in when you get a chance, and drives like a Honda. Bring back some of the engineering skills that Honda once stood for. And then start introducing a portfolio of EVs once people are more comfortable with the idea of plugging in. People seeing that they can easily use an EV for their daily errands with the gas engine never starting will eventually sell them on a future EV because that range anxiety will be lessened. The all EV leap is still a bridge too far, especially as recent sales numbers have shown. Baby steps. That's how you win people over.
  • Theflyersfan If this saves (or delays) an expensive carbon brushing off of the valves down the road, I'll take a case. I understand that can be a very expensive bit of scheduled maintenance.
  • Zipper69 A Mini should have 2 doors and 4 cylinders and tires the size of dinner plates.All else is puffery.
  • Theflyersfan Just in time for the weekend!!! Usual suspects A: All EVs are evil golf carts, spewing nothing but virtue signaling about saving the earth, all the while hacking the limbs off of small kids in Africa, money losing pits of despair that no buyer would ever need and anyone that buys one is a raging moron with no brains and the automakers who make them want to go bankrupt.(Source: all of the comments on every EV article here posted over the years)Usual suspects B: All EVs are powered by unicorns and lollypops with no pollution, drive like dreams, all drivers don't mind stopping for hours on end, eating trays of fast food at every rest stop waiting for charges, save the world by using no gas and batteries are friendly to everyone, bugs included. Everyone should torch their ICE cars now and buy a Tesla or Bolt post haste.(Source: all of the comments on every EV article here posted over the years)Or those in the middle: Maybe one of these days, when the charging infrastructure is better, or there are more options that don't cost as much, one will be considered as part of a rational decision based on driving needs, purchasing costs environmental impact, total cost of ownership, and ease of charging.(Source: many on this site who don't jump on TTAC the split second an EV article appears and lives to trash everyone who is a fan of EVs.)
